IAPR-1- Module 1 - FoC

1. Implementation of basic C programs using Literals,Consonants, Variables, Data types.

2. Implementation of different categories of operators.

Ex.No:1

Build a C program to demonstrate the usage of different types of literals: integer, float, character, and string.

Date : 26.12.25

Aim:

To build a C program that prints integer, float,character, and string literals on the console using the printf() function.

Algorithm:

Step 1:

Start

Step 2:

Include the standard input-output library: #include<stdio.h>.

Step 3:

Inside the main() function, use printf() to display each literal along with its size in bytes using sizeof() :

3.1 Integer literal (e.g., 10) using %d

3.2 Float literal (e.g., 3.14) using %f

3.3 Character literal (e.g., 'A') using %c

3.4 String literal (e.g., "Hello C") using %s

Step 4:

Stop

Program:

Output:

Result:

Thus, the program was implemented and executed successfully, and the required output was obtained.

Ex.No:2

Build a C program to display the value of a macro constant and a constant variable.

Date : 26.12.25

Aim:

To build a C program that demonstrates the use of macro constants and constant variables.

Algorithm:

Step 1:

Start

Step 2:

Include the standard input-output library: #include<stdio.h>.

Step 3:

Define a macro constant PI with value 3.14159 using #define.

Step 4:

Inside main():

4.1 Declare a constant integer variable DAYS

4.2 Initialize it with the value 7

Step 5:

Use printf() to display the values of PI and DAYS.

Step 6:

Stop

Program:

Output:

Result:

Thus, the program was implemented and executed successfully, and the required output was obtained.

Step 1:

Start

Step 2:

Include the standard input-output library: #include<stdio.h>.

Step 3:

Inside main(), declare and initialize variables of types int, float, double, and char.

Step 4:

Display their values using printf().

Step 5:

Stop

Program:

Output:

Result:

Thus, the program was implemented and executed successfully, and the required output was obtained.

IAPR-1- Module 1 - FoC

Ex.No:4

Build a C program to perform arithmetic and bitwise operations on two integers entered by the user. The program should display: Arithmetic operations: addition, subtraction, multiplication, division, and remainder. Bitwise operations: AND, OR, XOR, left shift, right shift, and NOT.

Date : 26.12.25

Aim:

To build a C program that takes two integers as input and demonstrates the arithmetic and bitwise operations, displaying the results of each operation.

Algorithm:

Step 1:

Start

Step 2:

Include the standard input-output library: #include<stdio.h>.

Step 3:

Declare two integer variables a and b.

Step 4:

Prompt the user to enter two integers and read the input using scanf().

Step 5:

Perform arithmetic operations on a and b:

Sum (a + b)

Difference (a - b)

Product (a * b)

Quotient (a / b)

Remainder (a % b)

Step 6:

Perform bitwise operations on a and b:

AND (a & b)

OR (a | b)

XOR (a ^ b)

Left shift (a << b)

Right shift (a >> b)

Bitwise NOT of a (~a) and b (~b)

Step 7:

Display the results of all operations using printf().

Step 8:

Stop

Program:

Output:

Result:

Thus, the program was implemented and executed successfully, and the required output was obtained.

IAPR-1- Module 1 - FoC

Ex.No:5

Develop a C program to check whether a given character is a vowel, consonant, digit, or special symbol using the ternary operator.

Date : 26.12.25

Aim:

To develop and implement a C program that classifies a character as a vowel, consonant, digit, or special symbol using the ternary operator.

Algorithm:

Step 1:

Start

Step 2:

Include the standard input-output library: #include<stdio.h>.

Step 3:

Input a character ch from the user.

Step 4:

Check if ch is a digit ('0' to '9').

If true → Print "Digit" → Go to Step 8.

If false → Go to Step 5.

Step 5:

Check if ch is an alphabet letter ('A' - 'Z' or 'a' – 'z').

If true → Go to Step 6.

If false → Go to Step 7.

Step 6:

Check if ch is a vowel (a, e, i, o, u or A, E, I, O, U).

If true → Print "Vowel" → Go to Step 8.

If false → Print "Consonant" → Go to Step 8.

Step 7:

Print "Special Symbol".

Step 8:

Stop
